XtOpenApplication(3Xt)		XT FUNCTIONS	       XtOpenApplication(3Xt)



NAME
  XtOpenApplication, XtVaOpenApplication - initialize, open, or close a
  display

SYNTAX
  Widget XtOpenApplication(app_context_return, application_class, options,
  num_options, argc_in_out, argv_in_out, fallback_resources, widget_class,
  args, num_args)
	XtAppContext app_context_return;
	String application_class;
	XrmOptionDescRec* options;
	Cardinal num_options;
	int* argc_in_out;
	String* argv_in_out;
	String* fallback_resources;
	WidgetClass widget_class;
	ArgList args;
	Cardinal num_args;

  Widget XtVaOpenApplication(app_context_return, application_class, options,
  num_options, argc_in_out, argv_in_out, fallback_resources, widget_class,
  ...)
	XtAppContext app_context_return;
	String application_class;
	XrmOptionDescRec* options;
	Cardinal num_options;
	int* argc_in_out;
	String* argv_in_out;
	String* fallback_resources;
	WidgetClass widget_class;

ARGUMENTS

  app_context_return
	    Specifies the application context.

  application_class
	    Specifies the class name of this application, which usually is
	    the generic name for all instances of this application.

  options   Specifies how to parse the command line for any application-
	    specific resources.	 The options argument is passed as a parame-
	    ter to XrmParseCommand.  For further information, see Xlib - C
	    Language X Interface.

  num_options
	    Specifies the number of entries in the options list.

  argc_in_out
	    Specifies a pointer to the number of command line parameters.

  argv_in_out
	    Specifies the command line parameters.

  fallback_resources
	    Specifies resource values to be used if the application class
	    resource file cannot be opened or read, or NULL.

  widget_class
	    Specifies the widget class of the shell to be created.

  args	    Specifies the argument list to override any other resource
	    specification for the created shell widget.

  num_args  Specifies the number of entries in the argument list.

  ...	    Specifies the variable argument list to override any other
	    resource specification for the created shell widget.

DESCRIPTION
  The XtOpenApplication function calls XtToolkitInitialize followed by
  XtCreateApplicationContext, then calls XtOpenDisplay with display_string
  NULL and application_name NULL, and finally calls XtAppCreateShell with
  appcation_name NULL, widget_class applicationShellWidgetClass, and the
  specified args and num_args and returns the created shell. The modified
  argc and argv returned by XtDisplayInitialize are returned in argc_in_out
  and argv_in_out. If app_context_return is not NULL, the created application
  context is also returned. If the display specified by the command line can-
  not be opened, an error message is issued and XtOpenApplication terminates
  the application. If fallback_resources is non-NULL, XtAppSet-
  FallbackResources is called with the value prior to calling XtOpenDisplay.

  XtAppInitialize and XtVaAppInitialize have been superceded by XtOpen-
  Application and XtVaOpenApplication respectively.
